教学素材 | 眼睛里的漂浮物是什么？

眼睛里的漂浮物是什么？What are those floaty things in your eye?词汇：考研 | 句法：六级| 文本：考研刘立军供稿Have you ever noticed something swimming in your field of vision? It may look like a tiny worm or a transparent blob, and whenever you try to get a closer look, it disappears, only to reappear as soon as you shift your glance. But don’t go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater.你是否曾经注意到视野中有东西在游动？它可能看起来像一条小虫子或一个透明的斑点，而每当你试图仔细看时，它却消失了，只有在你转移视线时又重新出现。但别急着去冲洗眼睛！你看到的是一种常见的现象，称为“飞蚊症”。The scientific name for these objects is Muscae volitantes, Latin for "flying flies," and true to their name, they can be somewhat annoying. But they’re not actually bugs or any kind of external objects at all. Rather, they exist inside your eyeball.这些物体的科学名称是Muscae volitantes，拉丁语意为“飞舞的苍蝇”。正如其名，它们确实有些烦人。但它们并不是虫子，也不是任何外部物体，而是存在于你的眼球内部。Floaters may seem to be alive, since they move and change shape, but they are not alive. Floaters are tiny objects that cast shadows on the retina, the light-sensitive tissue at the back of your eye. They might be bits of tissue, red blood cells, or clumps of protein.“飞蚊”看起来像是活的，因为它们会移动并改变形状，但实际上，它们并不是生物。“飞蚊”是投射在视网膜（眼球后部对光敏感的组织）上的微小物体。它们可能是组织碎片、红细胞或蛋白质团块。And because they’re suspended within the vitreous humor, the gel-like liquid that fills the inside of your eye, floaters drift along with your eye movements, and seem to bounce a little when your eye stops.由于它们悬浮在玻璃体（一种充满眼球内部的凝胶状液体）中，“飞蚊”会随着眼球的运动而漂移，并在眼球停止移动时似乎轻轻弹跳。Floaters may be only barely distinguishable most of the time. They become more visible the closer they are to the retina, just as holding your hand closer to a table with an overhead light will result in a more sharply defined shadow.大多数时候，“飞蚊”几乎难以察觉。它们越靠近视网膜，就越明显，就像将手靠近桌面时，在顶灯下会产生更清晰的阴影一样。And floaters are particularly noticeable when you are looking at a uniform bright surface, like a blank computer screen, snow, or a clear sky, where the consistency of the background makes them easier to distinguish. The brighter the light is, the more your pupil contracts. This has an effect similar to replacing a large diffuse light fixture with a single overhead light bulb, which also makes the shadow appear clearer.当你注视一片均匀明亮的表面时，比如空白的电脑屏幕、雪地或晴朗的天空，“飞蚊”尤其显眼，因为背景的一致性让它们更容易被分辨出来。光线越亮，瞳孔收缩得越多。这种效果类似于用一盏顶灯替换大面积的散射光源，这也会使阴影变得更清晰。There is another visual phenomenon that looks similar to floaters but is in fact unrelated. If you’ve seen tiny dots of light darting about when looking at a bright blue sky, you’ve experienced what is known as the blue field entoptic phenomenon.还有另一种视觉现象看起来与“飞蚊”相似，但其实并无关联。如果你在注视明亮的蓝天时看到有微小的光点在飞舞，那么你经历的就是所谓的“蓝场内视现象”。In some ways, this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windows letting light through to your retina. The windows are actually caused by white blood cells moving through the capillaries along your retina’s surface.在某些方面，这与看到“飞蚊”正好相反。这里，你看到的不是阴影，而是让光线透过的小“窗口”。这些“窗口”实际上是白细胞沿着视网膜表面的毛细血管移动造成的。These leukocytes can be so large that they nearly fill a capillary causing a plasma space to open up in front of them. Because the space and the white blood cells are both more transparent to blue light than the red blood cells normally present in capillaries, we see a moving dot of light wherever this happens, following the paths of your capillaries and moving in time with your pulse.这些白细胞可能会大到几乎填满毛细血管，从而在它们前面形成一个血浆空间。由于这些空间和白细胞对蓝光的透明度比毛细血管中的红细胞更高，因此无论何时发生这种情况，我们都会看到一个移动的光点，沿着毛细血管的路径移动，并与脉搏同步。Under ideal viewing conditions, you might even see what looks like a dark tail following the dot. This is the red blood cells that have bunched up behind the leukocyte.在理想的观察条件下，你甚至可能看到光点后面有一个类似暗尾的东西。这是堆积在白细胞后面的红细胞。Some science museums have an exhibit which consists of a screen of blue light, allowing you to see these blue sky sprites much more clearly than you normally would.一些科学博物馆设有蓝色光屏展览，让你能够比平时更清楚地看到这些“蓝天精灵”。While everybody’s eyes experience these sort of effects, the number and type vary greatly. In the case of floaters, they often go unnoticed, as our brain learns to ignore them. However, abnormally numerous or large floaters that interfere with vision may be a sign of a more serious condition, requiring immediate medical treatment.虽然每个人的眼睛都会经历这类现象，但其数量和类型差异很大。对于“飞蚊”来说，它们通常会被忽视，因为大脑学会了忽略它们。然而，如果“飞蚊”数量异常多或体积过大，干扰了视力，则可能是某种严重疾病的征兆，需要立即就医。But the majority of the time entoptic phenomena, such as floaters and blue sky sprites, are just a gentle reminder that what we think we see depends just as much on our biology and minds as it does on the external world.但大多数时候，像“飞蚊”和“蓝天精灵”这样的内视现象只是温和地提醒我们，我们所“看见”的内容不仅取决于外部世界，也取决于我们的生物学特性和思维。【词汇】 1. blob n.（不规则的）斑点，团状物2. retina n. 视网膜3. clump n. 团块，聚集物4. vitreous humor n. 玻璃体液，玻璃状液5. entoptic adj. 眼内的，内视的6. leukocyte n. 白细胞7. capillary n. 毛细血管8. plasma n. 血浆，等离子体9. sprite n. 小精灵，幽灵（本文图片来源于摄图网，版权归摄图网所有)

Aren't naps the key to feeling alert, improving your memory and just generally having a great life? Well, they can be, but things aren't quite that simple.(Q1) It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. Our circadian rhythms are responsible for the notorious lull that many of us feel in the early afternoon. This is the best time for a nap. Some companies have installed sleep pods for their employees, hoping to benefit from increased productivity and cognitive performance. But it is also true that naps can cause problems.circadian adj. 生理节奏的，昼夜节律的 notorious adj. 声名狼藉的，众所周知的（常指不好的事情） lull n. 间歇，平静期 pod n. 小舱，隔间 cognitive adj. 认知的 Let's start by thinking about the length. (Q2) A true power nap should be less than half an hour. Any longer, and it becomes hard to rouse yourself from. Any benefits in terms of alertness are likely to disappear with the grogginess that results from a longer period of slumber.grogginess n. 昏昏沉沉，虚弱无力slumber n. 睡眠，微睡 This isn't the only issue. Naps have been linked to conditions such as diabetes, high blood pressure and cardiac problems. However, it's not clear whether these are direct results, or stem from the impact of napping on our sleep habits. (Q3) If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained.cardiac adj. 心脏的 ingrain v. 使根深蒂固 Of course, in the same way that naps can lead to bad sleep, it's also true that bad sleep can lead to wanting to take more naps. (Q4) So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case. Are there any potential health issues that could be causing insomnia? Or are work pressure stopping you from getting enough sleep?insomnia n. 失眠 Part III. KEYQ1.【答案】B【解析】细节题。题目出处：It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. 意为：“的确，小睡片刻能帮助人们更加清醒，提升记忆力和专注力，还能降低操作重型机械等作业时的风险。” 因此正确答案为B。 Q2.【答案】A【解析】细节题。题目出处：A true power nap should be less than half an hour. 意为：“真正的有效小憩时间应控制在半小时以内。。” 文章明确指出，有效小睡的时间应该少于半小时，超过这个时间可能会导致昏昏沉沉，并抵消小睡的益处，因此正确答案为A。 Q3.【答案】C【解析】细节题。题目出处：If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained. 意为：“如果你在下午两三点之后小睡，很可能会对夜间入睡能力产生负面影响。打乱睡眠周期会导致不良的睡眠习惯，而这些习惯本身又会变得根深蒂固。”因此正确答案为C。 Q4.【答案】B【解析】推理题。题目出处：So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case.

TRANSCRIPTHow to write a promptI don’t usually overhide myself, but in this video, we’re going over the only formula you will ever need to master prompting on ChatGPT and Google Bard. So, let’s get started. Hey friends, welcome back to the channel. If you’re new here, my name is Jeff. I work full time in tech. And if you’re anything like me, a couple months ago, you know prompting is an important skill to learn, but you’re not exactly sure why some prompts generate outputs that are super generic, while others give you precisely what you’re looking for. Since then, I’ve spent hundreds of hours taking prompt engineering courses and applying what I’ve learned in my daily life. (Q1) And so in this video, I’m sharing the six building blocks that make up a good prompt so that you can use this formula to consistently generate high quality outputs. The 6 Prompt ComponentsThe BasicsFirst, it’s critical to not only know what the six components are, task, context, exemplars, persona, format, and tone, but also know that there’s an order of importance to these six components. To show you what I mean, let’s use this simple example. I’m a 70 kg male. Give me a 3-month training program. The first part is context, followed by the task. The reason why the task is higher up in the form, the hierarchy, is if we just input the task without the context, there’s still some sort of meaningful output. But if we just give ChatGPT the context, nothing really happens. Put another way, (Q2)it’s mandatory to have a task in your process prompt. It’s important to include relevant context and exemplars. And it’s nice to have persona, format, and tone. When you think of writing your prompt, go down this mental checklist. So this formula will act as a constant reminder for you to include just enough relevant information when writing prompts. And as you’ll see in this next part, you do not need all six components in every prompt to have a good output. mandatory adj. 强制的，义务的#1 TASKNow let’s break down each building block with specific examples. (Q3) Starting with the task, the rule of thumb is to always start the task sentence with an action verb, generate, give, write, analyze, etc., and clearly articulate what your end goal is. It could be one simple task like generating a three-month training program or a complex three-step task like analyzing hundreds of user feedback, sharing the top three takeaways, and categorizing the feedback based on the team responsible for following up. #2 CONTEXT(Q4) The second component, context, is the trickiest to get right because technically there’s an infinite amount of information you can give. So I found asking myself these three questions to be super helpful in coming up with just enough information to get a good result from ChatGPT. First, what’s the user’s background? Second, what does success look like? And third, what environment are they in? Back to the workout example we now have, I’m a 70 kg male looking to put on 5 kg of muscle mass over the next three months. I only have time to go to the gym twice a week and for one hour each session. Give me a three-month training program to follow. Could I have added more background information? Of course, only prioritize the muscle groups that make me look good on Instagram. But the key to staying productive with ChatGPT and Bard is giving just enough information to constrain the endless possibilities. By the way, although this video is not sponsored, it is supported by those of you who subscribe to my paid productivity newsletter on Google Workspace Tips. Link in the description to learn more. #3 EXEMPLARS = EXEMPLESMoving over to the exemplars component, it’s just a fancy way of saying examples. (Q5) Basically all the research on large language models, LLMs, have shown that including examples within the prompt drastically improves the quality of the output. Starting with a simple example, this is a poorly written bullet point from a resume. We can now ask ChatGPT to rewrite this bullet point using this structure. I accomplished X by the measure Y that resulted in Z, which is actually best practice by the way, so actually do this in your resume. For example, I lowered hospital mortality rate by 10% by educating nurses in new protocols, which translates to 200 lives saved per year. exemplar n. 范例，样本Here’s a slightly more complicated example for interview prep. Based on my own resume, write me an answer to the interview question. What’s your biggest weakness? Use the STAR answer framework, situation, task, action, and results. Here instead of using a full blown interview answer as an example, which would be overkill, the STAR framework acts as an example structure for ChatGPT to follow. overkill n. 过度，过犹不及Last example, let’s say you need to write a job description. You give some context around the opening and ask ChatGPT to reference an existing job description. You might use this one I found on LinkedIn. The output will follow the same formatting and use the same professional HRE language, saving me a bunch of time. Main takeaway here, exemplars are not necessary for every prompt, but including a relevant example or framework will greatly improve the quality of your output. #4 PERSONAMoving along, the persona component is basically who you want ChatGPT and Bard to be. (Q6) And the pro tip here is to think of someone you wish you had instant access to with the task you’re facing. If you injured yourself working out, that person might be a physical therapist with experience helping athletes recover. If you’re a job seeker, that person might be a recruiter or hiring manager. If you’re working on a creative brief, that person might be a senior product marketing manager who’s great at storytelling. Pro tip, you can also name specific individuals, but I found the results to be good only when they’re famous enough, like Warren Buffett, Steve Jobs, Jeff Su. By the way, I just have to share this. We have a team offsite with a superhero’s theme. (Q7) So I asked ChatGPT to draft an email from Batman and it even included things like, please let Alfred know and signed off as the Dark Knight. So fictional characters work as well. And I’m actually going to use this. persona n. 角色，人物形象#5 FORMAT(Q8) The fifth component, format. The pro tip here is to literally close your eyes and visualize how exactly you want the end result to look like. A million likes on my Thirst Bomb Instagram photo. Damn it, didn’t work. Back to the user feedback example, I don’t want to read each sentence. So I asked ChatGPT to take all the feedback and output a table with three headers. The original feedback, the team responsible for following up and priority. And now I can copy this directly and paste it into a Google sheet. So by priority and filter by team. Other common formats include emails, bullet points, and code blocks. header n. 标题，标头But the one I found to be the most useful as a full-time working professional is paragraphs and markdown. For example, I just received a lengthy industry report from my director. First give me the three key takeaways, then summarize based on topic. Use H2 as section headers. Here is the report. Pro tip, whenever I use ChatGPT to proofread any document, I specify that all changes need to be bolded so I can easily see exactly what has been changed. #6 TONELet’s quickly go through the last component, tone, before we put all this together in one example. (Q9) The good news is tone is easy to understand. Use a casual or formal tone of voice. Give me a witty output, show enthusiasm, sound pessimistic. The bad news is we’re usually not very good at recalling the thousands of potential adjectives and adverbs at a moment’s notice. (Q10) So here’s a pro tip. Tell ChatGPT the feeling you’re going for. For example, I’m writing an email to a team I haven’t worked with before and I want to be taken seriously without coming off as too stuck up and cringy. Can you please give me a list of five tone keywords I can include in a prompt for ChatGPT? And look, now in the actual prompt, I can say, use clear and concise language and write in a friendly yet confident tone. EXAMPLE PROMPTPutting all this together, let’s look at this comprehensive prompt. You are a senior product marketing manager at Apple [Persona] and you have just unveiled the latest Apple product in collaboration with Tesla, the Apple Car, and received 12,000 pre-orders, which is 200% higher than target. [Context] Write an email to your boss, Tim Cookie, sharing this positive news. [Task and Format], The email should include a TLDR, too long, didn’t read section. Project background, why this product came into existence, business results section, quantifiable business metrics, and end with a section thanking the product and engineering teams. [Example structure] Use clear and concise language and write in a confident yet friendly tone. [Tone] Note that if I had an existing email to reference, I could delete the instructions around the structure and simply tell ChatGPT the email should follow the exact same format as the one I will share below and paste the email from before. By the way, you can compare the output from this prompt to that of a simpler prompt. I just launched a new product, the Apple car. I received 12,000 pre-orders. Please run email to my boss with this update. There’s a pretty big difference in terms of how generic and usable the end result is. Now that you know the basics of prompting, my next video is going to take you from beginner to pro, so make sure you’re subscribed for that. Check out my top 5 ChatGPT productivity tips for work. See you on the next video. In the meantime, have a great one.Part III. KEYQ1. A. 主旨题。根据“I’m sharing the six building blocks that make up a good prompt so that you can use this formula to consistently generate high quality outputs.”可知是视频的主要目的是分分享构成优质提示的六个核心要素，让大家能用这个公式持续生成高质量内容。因此答案为A。Q2. B. 细节题。根据“it’s mandatory to have a task in your process prompt”可知提示中必须有一个任务，这表明任务是最重要的组成部分。因此答案为B。Q3.D. 细节题。根据“Starting with the task, the rule of thumb is to always start the task sentence with an action verb...”可知任务部分应该以一个动作动词开头。因此答案为D。Q4. C. 细节题。根据“The second component, context, is the trickiest to get right because technically there’s an infinite amount of information you can give.”可知上下文是最棘手的，因为理论上，你可以提供无限量的信息。这表明上下文部分可以有无限的信息。因此答案为C。Q5. B. 细节题。根据“Basically all the research on large language models, LLMs, have shown that including examples within the prompt drastically improves the quality of the output.”可知研究表明，在提示中包含示例能大幅提升输出质量。因此答案为B。Q6. C. 细节题。根据“And the pro tip here is to think of someone you wish you had instant access to with the task you’re facing.”可知讲话者建议确定提示的人物角色时，应该设定为一个与任务相关的专业人士。因此答案为C。Q7. D. 细节题。根据“So I asked ChatGPT to draft an email from Batman and it even included things like, please let Alfred know and signed off as the Dark Knight.”可知讲话者提到，他让ChatGPT起草一封来自蝙蝠侠的电子邮件，包含了请通知阿尔弗雷德并以黑暗骑士的名义签字等细节，这是给出的一个综合提示的例子，其中包含了任务、角色和场景3个要素。因此答案为D。Q8. B. 细节题。根据“The fifth component, format. The pro tip here is to literally close your eyes and visualize how exactly you want the end result to look like.” 可知格式是闭眼能想象到最终结果的样子，也就是输出结果的预期结构和外观。因此答案为B。Q9. B. 推理题。根据“So here’s a pro tip. Tell ChatGPT the feeling you’re going for.”可知在使用提示时，应该指定输出的期望情感，即语气应该与输出的预期感觉相匹配。因此答案为B。 （本文图片来源于摄图网，版权归摄图网所有)

第12届教学大赛商务英语组特等奖潘紫萌授课

授课点评：潘紫萌老师在本次大赛中与来自全国各地的商务英语优秀教师展开激烈角逐，在教学理念、教学方法、课堂设计、英语素质、商务知识、教姿教态、师生互动等方面的表现都较突出，最后以总分第一荣获特等奖。潘老师以准确的英语发音先声夺人，丰富的表达方式、适中的语调语速和端庄的教姿教态也令人印象深刻。在课程设计环节，为实现其教学目标，她选择business ethics作为主题，介绍了教学目标、学生特征、以学生为中心和以产出为导向的教学理念，以及线上线下结合、传统和高科技媒体结合等丰富多彩的教学方式。这份介绍全面立体但简明扼要，为后面的演示（demo）课提供了一个很好的支撑。由于大赛的授课时间有限，潘老师突出重点，在演示课上只展示教学方案的第三步，即participatory learning 1 和 post assessment 1。她采用BOPPPS（bridge in, objectives, pre-assessment, participatory learning, post assessment, summary）模型，通过德国大众汽车减排作假、中国支付宝公益植树项目等案例，教学目标涵盖商务英语知识、技能、以及相关的伦理和价值观等。在短短的十几分钟里要达到这么多项教学目标绝非易事。潘老师通过一系列的短视频、多种教学方法（如听力填空、案例讨论、汉译英、样本对话补正等）以及活泼的师生互动，较好地实现了教学目标，显示出选手突出的课堂组织能力。商务英语教学起源于英美等国，因此基本使用本国素材、讲本国故事。传入中国后，主要使用外国素材、讲外国故事。令人欣喜的是，潘老师注意突出中国特色，多次引用中国案例，讲授中国故事，传播中国价值观。加上她出色的英语基本功和良好的师生互动，使得教学过程十分流畅，也没有不同文化同场展示的违和感。总而言之，潘紫萌老师在授课环节的各方面表现都很优秀。不足之处当然也有。首先， 8’13’’开始的讨论过于仓促，只有18秒， 8’31’’就结束了。由于讨论不充分，在随后的问答环节中，更多的回答似乎来自老师而不是学生。第二个是要增加教学过程的自然自发 (spontaneity)。不知是因为课前多次排练还是老师特意要求，学生的产出只有一次对话（17’40’’）相对自然，其他的多次回答虽准确无误，但都像中国小学生朗读课文或回答问题，语音、语调、语速都过于整齐合一，这不利于培养学生的英语实际表达能力。点评专家：陈准民
